NON-EXPLOSIVE PREPARATIONS AND PROCESS OF MAKING'SAME.

To all whom it may concern:

Be it known that I, ALBRECHT Ph.D., chemist, a Germany, Germany,

citizen of the Empire of residing at Hochst-on-the-Main, have invented certain new and Non-Explosive Preparations and Processes of Making Same, of which the following is a specification.

In U. S.

patent-application Ser. No. 7 92,465, filed September 29, 1913 is described a process by which non-explosive preparations can be obtained and which consists in incorporating 4 waste-liquors from sulfi'te cellulose or their essential components with nitro or dinitro or polynitro compounds, for example, such as salts of dinit-roand polynitro-phenols, of which sodium-dinitrocresolate, sodium-dinitro-phenolate, or the like, are illustrations, such compounds be-' ing in the following specification all comnitro-phenol compounds. p

In elaborating this invention, I have found that the explosiveness of the aforesaid compounds can also be prevented by adding to them inorganic salts, such, for instance, as Z1110 chlorid,

phates or the like, and that this ofl'ers the further advantage that, in so far as the preparations are to be used for the preservation of wood, the inflammability of the wood is lessened by such impregnation, the respective nitro compounds producing at the same time a mycocide efi'ect. Of the inorganic salts the most suitable for carrying out my present invention are those which are known to diminish the inflammability of wood, etc.

In other respects the method of carrying out the new process is the same as that set forth in 'said U. S. patent-application Ser. No. 7 92,465, filed September 29, 1913. Thus, for instance, a v capable of being transported and which even when artificially and completely dried' with caustic soda lye with about the same Specification of Letters Patent.

or one and a half times the quantity or less of zinc chlorid. By allowing the pastes thus obtained to dry at 'a moderately high temperature, for instance in vacuo, solid products are obtained which, even when sud'- denly heated, do not explode but only glow faintly." In cases where it is not intended to suppress entirely the explosiveness of nitro-bodies but only to diminish it, con

siderably less of the zinc chlorid is added.

Having now described my invention, what I claim, is:

1. The process which consists in incorporating with explosive nitro-phenol compounds having mycooide properties, fireproofing inorganic salts in quantity sufficient to render the-mixture non-explosive.

2. The process of manufacturing non-explosive preparations, which consists'in incorporating with alkali-nitro-phenol compounds having mycocide' properties in organic salts which are capable of diminish- 7 ing the inflammability of combustible material;

3. As new products,the preparations obtainable by incorporating with explosive nitro-phenol compounds having mycocide properties, fireproofing inorganic salts in quantity suflicient to render the mixture non-explosive.

4. As new products having mycocide pmpertiesythe preparations obtainable by .incorporating inorganic salts with sodiumdinitro-phenolate, said preparations showing on the one hand the reactions of the sodiumrdinitrophenolate and on the other hand those of the said inorganic salts.

5. As new products having 'mycocide properties, the preparations obtainable by incorporating zincchlorid with sodium-dinitro-phenolate, said preparations showing on the one hand the dinitrohenolate and on the other hand those 0 the zinc chlorid.

In testimony whereof Iaflix my signature inpresence of two witnesses.
